Shirogane Takeru wakes up one morning to find a beautiful young woman sleeping in his bed; and an infuriated Kagami Sumika, Takeru's neighbor and childhood friend, finding both of them in inapropiate circumstances. The young woman, Mitsurugi Meiya, is the heiress to a financially powerful family and is determined to be Takeru's bride. Meiya soon joins Takeru and Sumika's school to get closer to the main character. As the game progresses, both girls compete for Takeru's affection, forming a bond of friendship between them and other girls from the same class.

Although Extra does take place in an alternate world to Unlimited and Alternative, it is still a necessary part of the story, as the Takeru in Unlimited and Alternative was originally from the Extra world.

Muv-Luv Extra consists of 5 different routes, each following one of the 5 heroines.

The two main routes, starring Kagami Sumika and Mitsurugi Meiya, consist on very similar content through a long portion of the playthrough, only changing slightly depending on the options you choose, during certain events, and the ending.

The three side routes differ in large manner plot-wise from the two main routes. Sakaki Chizuru, Ayamine Kei, and Tamase Miki are the respective heroines of each route. Sakaki Chizuru's and Ayamine Kei's route are known for having more drama than comedy, while Tamase Miki's being generally more light-hearted, consisting of plenty more comedy than drama.
